Workflow

Design process in DIALux

DIALux fits perfectly into your existing workflow. It supports many open interfaces and file formats such as IFC, STF, DWG, DXF, IES, or LDT. So for example you can comfortably use data from a different CAD software and create a lighting design in DIALux. And finally export your results for documentation or communicate them to contractors or clients.
